Razor blade stropper



@Qi H5, N MERCER Zlg@ RAZOR BLADE STROPPER Filed Jan, 25, 1935 PatentedOct. 15, 1935 1 Claim.

This invention relates to improvements in razor bade stropping devices,and one of its objects is to provide a stropper which can be made in twopieces, one of which includes a handle and blade centering means orclamping member, and the other of which consists of a clamping memberadapted to straddle the other clamping member and produce edge pressureon the razor blade to be stropped.

Another object of the invention is to provide such a stropper for safetyrazor blades of the two edged type, with curved side surfaces whichapproximately match each other, and which afford a good stropping anglefor the cutting edge of the safety razor blade, this being provided onthe detachable clamping member which straddles the blade centeringmember formed on the handle.

A further object is to provide a blade centering pin formed out of thestock of the handle, by a stamping operation, under which the detachableclamping member will slidably interlock.

A further object of the invention is to provide a razor blade stropperwith a detachable clamping member which straddles the blade centeringmember of the handle, and slidably interlocks with the centering pinsthereof.

With the above and other objects in view the invention consists incertain new and useful constructions, combinations, and arrangements ofparts, clearly described in the following specification, and fullyillustrated in the accompanying drawing, in which:-

Fig. 1 is a plan view of the stropper with a blade carried thereby.

Fig. 2 is a longitudinal central sectional view taken on line A of Fig.l, looking in the direction of the arrow.

Fig. 3 is a plan View of the handle member, 40 with the detachableclamping member removed.

Fig. 4 is a transverse sectional view, taken on line B of Fig. l,looking in the direction of the arrow.

Fig. 5 is a side view of the detachable clamping member. o

Fig. 6 is a vdetail transverse sectional view, taken on line C of Fig.3, on an enlarged scale.

Fig. 7 is a central longitudinal sectional view, on an enlarged scale.

Fig. 8 is a transverse sectional View of a modified form.

Fig. 9 is an inside plan view thereof, showing the clamping member on anenlarged scale, before being completed.

Fig. 10 is a side elevation thereof.

Referring to the accompanying drawing illustrating practicalconstruction of my invention 5 designates the handle member, which isprovided with an integral blade carrying plate 6, which forms the baseblade clamping member or element, and which is provided with a pluralityof struck-out T-shaped lugs or blade centering pins l, 8 and 9. Each ofthese lugs includes the blade retaining head I0 which extendstransversely of the bar, and the legs II and I2, all of which arestamped from the stock of the blade. The head I5 of each projection isoffset relative to the legs I I and I2. The heads of the three retainingpins or projections are disposed in approximately the same common plane,and the legs are longitudinally aligned with each other.

At the inner end of the blade carrying plate 6 at its junction with. thehandle 5 a forwardly extending laterally off set lug I5a is providedwhich is designed to overlie the adjacent end of the clamp leg I5 torestrain a retained blade against vibration.

The two edge blade I3 is placed over the centering pins or projections,and then the detachable substantially U--shaped clamping member 2 I4 ismounted in place. For this purpose the member I4 is provided with a legI5, Which is formed with 'a longitudinal slot I6, to receive the headsI0 of the projections, and with a leg Il, which is adapted to havespring bearing contact with the bottom or outer face of the baseclamping member E. The two legs I5 and I'I are united by the bend I8.When the bottom member or leg Il is wholly disengaged from the member 6,it will spring slightly toward the member 3 I5. The member 6 is formedwith an L-shaped lug 6a, designed to engage the inner end of the splitleg I5, so as to retain the blade against vibration. The inner end ofthe leg il is slightly bevelled at Il', to permit of easy mounting. Theside edges Isa and I6b of the slot I6 are slightly relieved so that theheads I 0 of the retaining projections will be ilush with the outersurface of the leg I5.

The legs I5 and I 'l of the detachable clamping member I 4 aretransversely curved outwardly in convex form, so that both outer facesof the stropper will be alike, and the riding edge on each side of thedevice, will provide a proper stropping angle for the stropping of theblade.

The handle may be provided with facing strips 5a, secured thereto bymeans of eyelets 5', and 5".

As shown in Figs. 8, 9 and 10 the detachable clamping member may beformed with inturned side flanges I9 and 20, formed on the plate member2l, which are spaced apart to providethe longitudinal slot 22, whichslidably receives the heads l) of theY connecting pins or projections.The other leg 23 is then bent into U-shaped relation to the member orleg 2 i, as shown in Fig. 10, so that the device Will straddle the baseclamping member 6, which is left unchanged. This form of constructionprovides a detachable clamping member in which the coupling slot isconcealed, but the function and operation of the coupling remainssubstantially the same, except that spring tension may be developed inthe flanges i9 and 2S.

The outside or external faces of the legs of the detachable clampingmember have approximately equal convex curves, sothat the stroppingangle on each side of the device will be approximately the same, anduniform sharpening .of the razor blade edge will take place.

After a safety razor blade has been clamped between the clampingmembers, the device is placed on a razor strop and rocked by hand fromone position to the other, so that one edge of the blade will bestropped When the stropper is shifted in one direction, and the oppositeedge on the same side of the'blade, will be stropped When the stropperis shifted in the opposite direction.

Having described my invention I claim:-

A razor blade holder comprising a handle having a longitudinallyextending blade-carrying plate equipped with a plurality of bladecentering lugs, said lugs being stamped from said plate and each havinglegs with an offset head connecting them and extending transversely ofthe plate, a U-shaped blade-clamping member to endwise straddle saidblade-carrying plate and having one leg provided with a longitudinalslot to receive the legs of said lugs and iit under the heads thereof,the other leg of said clamp resiliently engaging the opposed face ofsaid plate to hold 20 the clamp in operative position.
